PRINTING DEVICE.

Specification of Letters Patent.

Patented Apr, 11, 1916.

Application filed April 22, 1915. Serial No. 23,080.

' upon the surfaces of sidewalks, streets and floors, and the object of my improvement is to provide a device which may be suspended and carried by ones hand as he walks along a sidewalk or street and which, if it be abruptly lowered to engage with the surface of such sidewalk or street for an instant of time, shall operate to print a sign or advertising matter on the surface of such sidewalk or street. I accomplish this object by devices illustrated in the accompanying drawings wherein Figure 1 illustrates a structure embodying my invention by a View partly in side elevation and partly in vertical mid-section, and Fig. 2 is a view of the same in horizontal cross-section on broken line w, m of Fig. 1.

Referring to the drawings, throughout which like reference numerals indicate like parts, 3 is the circular wall of a container whose bottom wall 4 is secured to the lower edges of said circular wall 3 by metal tacks 5, which tacks 5 also serve to secure the lower edges of a bottomless cloth bag 6 to the edge portion of said bottom wall 4, whereby said bottom wall 4 may serve as a bottom for said bag 6. The top of the bag 6 is provided with suspension strings 7 which, in a well known manner, as indicated in Fig. 1, may gather the top edges of said bag 6 to close it.

The bottom wall 4 of the container is made of stiff sheet material of little thickness, as of thin sheet metal or vulcanized fiber of sheet form and is provided with numerous small perforations which are disposed with relation to each other to form desired words, characters and symbols of a sign or advertising matter, as for example,

the words 0 timo ci ars as indicated in Fig. 2, by the numerous small circles. Obviously, such perforations may be of other forms than circles so long as they are disposed in such relation to each other as will cause them to represent desired words or symbols. Such bottom wall 4 thus serves as a stencil plate through which, in a manner well known, coloring matter may gain access to a surface upon which words or symbols are to be printed.

The operation of my sign printing device 1s as follows: The bag 6 is opened and the container is charged with a quantity of dry powdered material, of a desired color, as powdered chalk, whereupon the strings 7 are pulled to close the top of the bag 6, then the bag 6 is suspended and carried by ones hand along a sidewalk or street and at desired points thereon the operators hand is lowered abruptly to cause the bottom wall 4 to make a violent momentary contact with the surface of such street or sidewalk to sift portions of the powdered material through the perforations 011 to the surface of such sidewalk or street to which it will adhere in the form of the words or advertising matter represented by said perforations. Thus one may print a conspicuous advertisement at numerous successive points as he walks uninterruptedly along a sidewalk or a street.

Manifestly, if it be desired, the circular wall 3 may be dispensed with in which case the bottom edges of the bag 6 would be suitably secured to the edge portion of the bottom wall 4, but in practice I find the circular wall 3 in some degree prevents the bottom wall 4 from becoming distorted or deformed.

Obviously changes may be made in the forms, dimensions and arrangement of parts of my invention without departing from the spirit thereof.

What I claim is:

A device of the class described comprising a container consisting of a side wall, a bottom wall that is perforated to serve as a stencil plate, and a bottomless bag-like structure whose lower end portion is extended around the sides of said side wall and securely connected therewith. I

In witness whereof I hereunto subscribe my name this twelfth day of April, A. D. 1915.
